DETAILED DESCRIPTION
[0063] Having summarized various aspects of the present disclosure, reference will now be made in detail to that which is illustrated in the drawings. While the disclosure will be described in connection with these drawings, there is no intent to limit it to the embodiment or embodiments disclosed herein. Rather, the intent is to cover all alternatives, modifications and equivalents included within the spirit and scope of the disclosure as defined by the appended claims.
[0064]
[0065] In the embodiment depicted, various elements of the present invention are shown in one of many different possible configurations. It is contemplated that in some embodiments, the physical arrangement or configurations of one or more elements of the present invention may be positioned differently from the arrangement generally disclosed in
[0066] In one embodiment water may be extracted by driving air in through the inlet 112 by the exemplary fan 114 into the cooling chamber 122 where the cooling means 126 may reduce the temperature of the driven air until water may be extracted through condensation. Extracted water as condensation is collected or gathered together in the means for collecting extracted water 132, and diverted to the reservoir, not pictured by path 134. Exhaust comprising dehumidified air may exit the system through an outlet, not pictured, by path 116.
[0067] The inlet 112 may be operative to receive ambient air into the system. In some instances, the inlet 112 may comprise at least one filter, preceding the cooling chamber 122, to prevent the entry of dust, bugs, and other particles into certain portions of the system.
[0068] The means for driving ambient air is drawn as a fan 114 in the exemplary embodiment, however, it is s contemplated that means for driving air into the system by way of the inlet 112 may alternatively or additionally comprise a fan, compressor, or air pressure increase device. In some embodiments, the means for driving ambient air into the system further comprises a convergent divergent nozzle known to those of ordinary skill in the art.
[0069] The cooling means 126 may be operative to cool the chamber 122 in order to cause condensation of water in the air driven into the system. The cooling means 126 may also cool the cooling member 124. The cooling means 126 may be, for example, a thermoelectric cooler, a water-assisted cooler, effluent air, or coolant. In an embodiment where the cooling means 126 is a thermoelectric cooler, the cooling means 126 may, for example, operate on principles of thermoelectric, Peltier, or refrigeration style cooling as known to those of ordinary skill in the art. In instances when the cooling means 126 requires power to operate, the system may further comprise a power supply, not shown, in electrical communication with the cooling means 126.
[0070] In instances where effluent air is utilized as a cooling means 126 it may utilize exhaust air. The exhaust air may for example be configured to contact the ambient air entering the system. It is contemplated that the exhaust air may be operative to cool the ambient air through thermodynamic principles. As a clarifying example and without limitation, the exhaust air be operative to pre-cool the ambient air as it enters the cooling chamber.
[0071] The exhaust air may leave the system through an outlet located off of path 116 from the means for collecting extracted water 132. Such outlet may comprise any means operative to allow air to pass through. For example, and without limitation, the outlet 116 may be an opening, nozzle, or pipe. It is contemplated that the outlet may further comprise at least one filter configured to prevent particles from entering the system through the outlet. The outlet may be located on any surface of the system. Providing a plurality of outlets throughout the system may beneficially reduce air pressure and energy required to operate the system. However, it is contemplated that manipulating the pressure of air in the system may aid water extraction. In one exemplary embodiment, the outlet may be disposed along ductwork or tubing defining the path 134 the cooling chamber 122 and the reservoir. It is contemplated that the outlet may be configured such that any expelled exhaust air is directed away from the inlet 112. In another embodiment however, the outlet 116 may be configured such that it is located near the inlet 112. Indeed, in some embodiments, it may be possible to recycle air through the system without departing from the invention in order to extract remaining moisture.
[0072] The reservoir may be connected to the cooling chamber 122 off of path 134 from the means for collecting extracted water 132 as well. In some embodiments the reservoir 134 may comprise a one-way valve to allow the extracted water to flow into the reservoir 134 but prevent backflow through the means for collecting extracted water 132 and/or into the cooling chamber 122.
[0073]
[0074] In the embodiment shown in
[0075]
[0076]
[0077] In some embodiments, the air separator 222 may be operative to direct exhaust air so it can be utilized as the cooling means 126. The directed exhaust air may, in one embodiment, be operative to perform pre-cooling of the air entering the system. This is accomplished by contacting the ambient air entering the system with the directed exhaust air, thus reducing the temperature of the air as it enters the system. The exhaust air may, for example, be air in which water has previously been extracted by the system. It is contemplated that using the exhaust air as a cooling means 126 it may reduce overall energy consumption. It is further contemplated that using the exhaust air as a cooling means 126 may increase the water yield since recycled air may be subject to cooling and water extraction multiple times.
[0078] The air separator 222 may be further operative to direct air out of the system as exhaust through one or more outlets discussed above. In some instances, the air separator 222 may be operative to direct exhaust the one or more outlets following after such air has been recycled through the system for pre-cooling.
[0079]
[0080] The air flow module 310, for instance, may comprise the inlet 112, means for driving ambient air 114, outlet 116, and duct 212 referenced with respect to exemplary embodiments in
[0081] The cooling module 312 may comprise the cooling chamber 122, cooling member 124, and cooling means 126 shown in
[0082] The collection module 314 may comprise one or more reservoirs. In some embodiments, the collection module 314 may further comprise a collection means operative to assist moving water through the system and into the reservoir 134. In some instances, the collection means may comprise a device that may, for example, be operative to collect the extracted water through on principles of gravity, vibration, centrifugal force, and pushing. For instance, the collection means may comprise one or more plates or surfaces tilted downward to cause condensation collected thereon to slide downward, under gravity, into the reservoir. A plate or surface may be in electrical communication with a motor that causes such plate or surface to shake or spin, causing condensation collected thereon to flow into the reservoir. Likewise, a motorized squeegee may be operative to push condensation into the reservoir. Thus, it may be seen that the particular collections means will not limit the invention. In any event, the power module 320 may be connected to the collection means as well.
[0083] As shown in
[0084] The means for purifying water may for example be one or more filters, an ultraviolet light, heat, or chemicals. In one embodiment, when the means for purifying water is one or more filters, such filters may, for example and without limitation, be located on the entry of the reservoir 134 shown in
[0085] The means for sanitation may also be connected with the power module 320. For example and without limitation, the means for sanitation may be ultraviolet lights that receive power from the power module 320. It is contemplated that in such an example, the ultraviolet lights may be located within reservoir 134 shown in
[0086] Alternatively, or in addition to the foregoing, the sanitation module 316 may comprise a heating source operative to increase the temperature of the extracted water as a means for purification. The heating of water for purification is well understood in the art. It is contemplated that the heating source may be connected to the power module 320.
[0087] The sanitation module 316 may alternatively or additionally comprise chemicals as a means for purifying extracted water. As an example, and without limitation, the chemicals may comprise non-toxic levels of chlorine sufficient to disinfect extracted water. However, a person of ordinary skill in the art will understand other chemicals for purifying water and the concentrations used to practice the invention.
[0088] In some embodiments, the sanitation module 316 may be located in the distribution module 318 rather than the collection module 314. For example, a filter comprising the sanitation module 316 may be located within the distribution module 318, such that the water is purified as it is leaving the system.
[0089] The sanitation module 316 may additionally be an independent module (not shown). For example, the extracted water may enter into the sanitation module that is not within any of the cooling module 312, collection module 314, or distribution module 318.
[0090] A distribution module 318 in accordance with one embodiment of the invention may comprise means for distributing the extracted water. As shown in
[0091] It is contemplated that the distribution module 318 may be configured in a manner operating on principles of gravity. For example, and without limitation, the means for distribution, such as a tube or valve, may be located at or near the bottom of the reservoir. In such an example, gravity may allow for the water to exit the system as it flows downward toward such tube or valve.
[0092] In another embodiment, the means for distributing extracted water may be connected to the power module 320. For example, a pump may be connected to the power module 320 and operative to distribute water from the system.
[0093] In another embodiment, the means for distributing extracted water may be user operated. For example and without limitation, the means for distributing extracted water may allow the user to open the reservoir and physically remove the extracted water, as desired. As a clarifying example, the distribution module may comprise a coverable opening in the reservoir, that can be accessed and through which water can be transferred to another container outside of the system. In a further clarifying example, system may be configured such that the distribution module 318 comprises the reservoir, and the distribution module is configured to be removable from the system with the extracted water still within the reservoir. In another example, a manual or electric pump may be operated on demand by a user to pump the extracted water out of the system.
[0094] As shown in
[0095] The at least one sensor of the sensor module 332 may be distributed amongst and within other modules comprising the system and further be configured to detect at least one variable selected from, for example only and not limitation, moisture level, system or module temperature, pressure within certain modules, power use as by or among certain modules, and water quality, or combinations thereof.
[0096] In one embodiment, the at least one sensor may be located within the air flow module 310. The at least one sensor in the air flow module may, as a non-limiting example, be operative to detect the amount of moisture, or humidity, in ambient and/or exhaust air. As an example, sensors in the air flow module 310 may for example be located on the inlet and outlet to measure the moisture of ambient air and the cool, dry air leaving the system, respectively. In such an example, the control module 330 may be operative to adjust system operations in order to reduce the moisture in the cool dry air and further to increase water yield.
[0097] In another example, the at least one sensor may be located within the cooling module 312. For example, the at least one sensor may be operative to detect the temperature in the cooling module 312. As another example, the at least one sensor may be operative to detect the pressure in the cooling chamber. The control module 330 may be operative to adjust cooling member to increase water yield. For example, the control module 330 may reduce the temperature of the cooling member to increase the water yield.
[0098] In a further example, the at least one sensor may be located within the collection module 314. As a non-limiting example, the at least one sensor may be located at the entrance of the reservoir to detect how much extracted water is entering the reservoir or moisture levels within the reservoir. Control module 330 may receive the detected moisture level as detected by the exemplary sensor, and be configured to run or halt operation of the system accordingly. If a the sensor detects moisture levels above a predetermined threshold in the reservoir, for example, the control module 330 may be operative to prevent the system from operating until the water level is reduced to some level below such threshold.
[0099] In another example, the at least one sensor in the reservoir 134 may be operative to detect temperature.
[0100] In an additional embodiment, the sanitation module 316 may comprise at least one sensor. As an example, the at least one sensor may be operative to measure water quality and comprise, without limitation, a pH analyzer, conductivity sensor, and/or turbidity meter. The control module 330 may, for example, be operative to detect water quality and determine whether extracted water is fit for consumption or general use.
[0101] In another embodiment, the distribution module 318 may comprise at least one sensor. For example and without limitation, it is contemplated that the at least one sensor in the distribution module 318 may be operative to measure the amount of water leaving the system. In such an example, the control module 330 may be operative to prevent or allow water to leave the system.
[0102] The power module 320 may comprise a power supply as, for example and not limitation, a battery or utility grid. In instances when the power supply is a battery, the battery may for example be rechargeable. The battery may be, without limitation, recharged by solar, wind, or the utility grid.
[0103] As shown in
[0104] As another non-limiting example, the control module 330 may be operative to receive the temperature from sensors in electrical communication with different components of the system that are operated by the power module. For example, the control module 330 may receive information relating to the temperature of the means for driving ambient air 114 as shown in
[0105] In light of the foregoing, it may be recognized that sensor module 332 may comprise at least one type of sensor located in multiple modules. That is, the sensors may, for example and without limitation, be operative to detect the same variable as one another in different modules.
[0106] In another example, at least one sensor may be located externally from the system. For example, an at least one external sensor may be located on an exterior surface of the system. or at some distance away from, but in communication with, aspects of the system. In such an example, the control module 330 may be operative to utilize data received from the sensors to improve efficiency. For example, the external sensor may be operative to detect moisture levels, temperature, or air flow. It is contemplated that the control module 330 may be operative to analyze data received from the at least one external sensor to optimize the system for water recovery or to increase energy efficiency. For example, if an external sensor detects low moisture in the ambient air, the control module 330 may be operative to prevent the system from operating for lack of sufficient water available for extraction. As a further example, if an external sensor detects low ambient temperature, the control module 330 may be operative to allow the system to operate. Whereas in instances of high temperature the control module 330 may prevent the system from operating until the outside temperature has been reduced. Thus, it may be seen that the control module, and various sensors, may be configured to automatically execute energy saving operations in response to certain detected conditions.
[0107] The control module 330 may be further operative to communicate with a second device. For example, the second device may be a computer, cellular device, tablet, or other devices operative to receive communication. The control module 330 may be operative to communicate over wired or wireless communication. The control module 330 may send information collected from the sensor module 332. It is contemplated, that the control module 330 may receive information relating to desired outcomes, for example, improved water yield.
[0108] The control module 330 may also be configured to monitor conditions related to safety. In one exemplary embodiment, the control module 330 may be operative to analyze data received from the sensor module 332 and determine whether the system is operating within pre-determined safe parameters. If the system is operating outside of the pre-determined safe parameters, it is contemplated that the control module 330 may be operative to execute a safety step such as, for example, halting system operation, sending a notification to the second device, executing an alarm, and/or combinations thereof. In some embodiments, the alarm, may be a light, noise, or other suitable method of raising an alarm.
[0109]
[0110] Such exemplary inlet 402 may be connected to the means for driving ambient air 404 such that the ambient air may be taken into the system through to the cooling chamber 406. The cooling chamber 406 may comprise cooling means 410 configured to cool the cooling member 408 and the cooling chamber 406, thus cooling air driven in to the cooling chamber. In this exemplary embodiment, the cooling chamber 406 may then be connected to the reservoir 412 and the outlet 414. It is contemplated that this is only one of many configurations for the outlet 414. For example and without limitation, the outlet 414 may be located in the reservoir 412 or at some point along any means for connecting the reservoir 412 and the cooling chamber 406, such as pipes or ductwork.
[0111]
[0112] Thus, it may be seen that in the exemplary embodiment of
